I tell yeeah, my buddy has a 04 YFZ 450. We ride fairly hard, lot of hill climbing and jumping. He has had 5x's more problems with his YFZ than I had, this mainly with his eletrical system. He sold his o3 becauase he had problems with it too! I tried to convine him to buy a Banshee, yet he goes, "No way too much work!" Im just tust thinking to myself wtf
